Grapevine named Ison

ABSTRACT

A cross between the female variety Sugargate and the pollen parent variety Senoia, to produce an improved variety of self-fertile muscadine grape.

DESCRIPTION OF THE VARIETY

A cross between the female variety Sugargate and the pollen parentvariety Senoia.

The primary objective of the breeding was to produce an improved varietyof muscadine grape. The fruit of the new variety is large and bronze andhas a dry stem scar. Other fruit characteristics of the new varietyinclude even ripening, high sugar content and long shelf life. The newvariety is self-fertile, as well as productive and vigorous.

In comparison with both the seed and the pollen parent, the new varietyis similar in size to the seed parent and resembles in color the seedparent. The new variety is larger than the pollen parent. The fruit ofthis new variety contains on the average of from 20 to 21 percentsoluble solids, which sugar content is higher than the pollen parent.The present variety yields approximately 4 to 6 tons per acre in testsconducted at Ison's Nursery & Vineyards, Brooks, Ga. The taste of thisfruit is outstanding, having an excellent flavor.

Asexual reproduction of the new variety either by soft wood cuttings orby layering as performed at Brooks, Ga. shows that the foregoingcharacteristics and distinctions come true to form and are establishedand transmitted through succeeding propagations.

The accompanying photograph shows a typical specimen of the vegetativegrowth and fruit of the new variety when the fruit is ripe and ready forpicking and as depicted in color as nearly true as it is reasonablypossible to make the same in color illustration of the characteristics.
